This invention relates to devices as applied to fusible, meltable and soluble materials, in bar or block form, to act as a gage indicative of the quantity Proprietors of dispensed.

' plumbing establishments,

where considerable quantities of solder are used, find it desirableto check the amount of such material issued to their workmen to be used on their jobs, as a precaution and deterrent from pilfering, but up tothe present time are unable manner.

It is therefore an object of the present invention to pro todo so in' a satisfactory vide a simple, practical'and Z inexpensive device whereby the number of bars issued may be checked and positively 1 accounted for by the workmen. A further feature is in the provision of means inseparably combined with such bars as will identify the same and therefore discourage illicit vendition. I

These important purposes are accom-' 'plished by the novel devices and combinations hereinafter described and illustrated in the accompanying drawing, forming part of this disclosure, and in which Figure 1 is a ventional bar of 'PSISPBCtlVB View of a consolder showing an application of the invention. I Figure 2 is a partial plan view of a solder bar, broken away to disclose the structure.

Figure 3 is a similar view showing a mod-V ified form of the check strip cast in the bar.

Figure it is a plan view of a solder bar carrying an adaptation of the check member.

A bar 10 of solder is shown in the several views, but it w ill be understood that any other materials capable of being molded into bar or block form, as tin, lead, rosin, wax, and likesubstances, which are melted or cons sumed inoperati on, are amenable to the process and protective system herein described. Disposed lengthwise of the bar, substantiallycentral of extending out at one or both ends, is a strip 11 of metal, such its width and thickness, and

as sheet iron, the same bearing on one of its projecting ends 12, a serial number,as at '13, and identification char acters 14.

Formed the longitudinal edges of the "192s. seriai no. 284,049.

strip are a series of corrugations or notches 15, so that when the mass is molded the strip is held permanently embedded, resisting any attempt at removal.

In the modified form shown in Figure 3' a-similar. strip- 11 is providedwith an eX-' tending end 12' bearing serial numbers, as I at 18, theedges of the strip being smooth and unbroken, and in the strip areopenings 16 into which the material flows, when melted or in a plastic condition, thus keying the strip permanently within the bar.

In the adaptation of the device shown in Figure 1, there is-set in the mold an anchor plate 17 having a tab 18 bearing a serial num- 'ber 19 and character--20,'s0 that asthe material is poured into the mold as'to cast the anchor plate rigidly into the bar, the numeral bearing tab extends outwardly from the side.

will be understood that changes in the form, I

arrangements, proportions, sizes and details thereof may bemade without departing from the scope ofthe invention as defined in the appended claim.

Having thus describedthe invention, what is claimed as new and desired to secure by Letters Patent, is:- 1

The combination of a mass of material of V predetermined weightwith an insert imbedded therein and havingfan end projecting therefrom, the said end having thereon indicia relating to the mass of material, 'thesaid material being of appreciably greater fusibil- 'ity than the'said insert. 7 V

In testimony whereof I have hereunto affixedmy signature.
